Yi-Application August 2, 1933, Serial No...683,2 7 5 Claims. "(01. 221*62)This invention relates to improvements in re= ceptacle closures forsitter cans and the'like, and has foran object to provide an improvedcon-' struction adapted to keep the container normally 5 closed, but soconstructed as to be readily operated for the discharge of the contentsby manual or digital pressure.

A further object of the invention is to pro-' vide a spring-operatedself-closing dredge of relatively simple construction, easy ofoperation,

without any projecting operative parts, and having a spring of such formand so related to the operative parts as eifectivelyto force the latterto closing position with appreciable force,'whereby accidental openingof the closure by infants will .be effectively guarded against.

The dredging device herein disclosed may be applied to containers ofvarying shape, and made of various kinds or combinations of material.Thus, if desired, for the purpose of economy, for

instance, the body of the container may be constructed of fibrousmaterial in combination with a metal operating unit.

Other objects will appear as the nature of the invention is betterunderstood, and the sameconsists in the novel form, combination andarrange Obviously, minor changes in detail and form of c'onstruction'maybe made without departing 3 mentby the lugs 8'. The apertures 7 willthen register-with: a multiplicity of the perforations 5 from thespiritand scope of the invention.

Referring more in detail to the drawing, a pre- 3 ferred embodiment ofthe invention is shown in" connection with an outer cap 1, suitablymounted uponithe'container 3, the central upper part of the capl. being.provided "with an opening14, the side wall of the cap also beingprovided with a pluralityiof perforations 5 through which the contentsof the can are dispensed when the slots 7 of an inner sleeve 6arebrought into register therewith: V v

a The inner slidable sleeve 6 is closed" at the top 11 and provided atthe sides with perforations 7,

shape that, when the inner. sleeve 6 is depressed, an efiective numberof openings 7 therein will register with a multiplicity of theperforations 5 in the'outer cap 1.- The bottom of the capl is providedwith. a plurality of inwardly turned lugs 8 which may be integral withthe wallof the cap 1', said lugs serving as supports for the which aresoarranged as to size, number and.

base of a. single volute helical spring 9, and serv-.

ing also to arrestthe downward movement of the inner movable sleevefiwhen the latter is operatively depressed,.the saidspring 9 resting atthe upper end against the closed top wall 11 of the: I inner movablesle'evefi.

.In operation,- when itisdesiredto dispense the contents of thereceptacle, the same is tilted and the inner movable sleeve 6 isdepressed by digital pressure until arrested in its downward movein theother member; whereupon someof the contents mayb'e dredged'or sprinkledthrough thealinedx'aperturesg The depression of the innermovable=sleeve16 is resiliently resisted by; the

spring 9 and;when" pressure has been removed, of

1 tion of closure, as shown in Figure 5.

the sleeve fi will be returned to the normal posilltwillvbe seen thatthe contents of the receptaclev may thus be easily dispensed wheneverdesired, by the positive'and' deliberate application of the-requiredforce .ito'the flattop '11 throughthe opening: ofsthe' outer 'cap';but-thatno discharge can occur accidentally by the casual handling ortoying of the container by an infant.

I claim:

1. A self-closing container top, comprising an inner sleeve open at itslower end and closed at the top, slidably engaged within a cap body ofthe same general configuration; the said cap body being provided withinwardly turned lugs at its lower end and a top wall provided with anopening; the said slidable inner sleeve being restricted in its downwardmovement by the said lugs at the lower end of the said outer cap body,and restricted in its upward movement by the partly closed top wall ofthe outer cap body; a helical spring placed within the said inner sleeveand resting at its lower end on the said lugs at the. lower end of theouter cap body and pressing at its upper end against the closed top wallof the inner sleeve, it being so disposed as to normally force theclosed top of said inner sleeve against the partly closed-g;

top of the outer cap body; the side walls of the inner slidable sleevebeing provided with'aperturesi'f so disposed as to permit them toregister with per forations in the side wall of the saidzoutercap body,when the said inner sleeve is in a position of full depression, andcompletely out of register when all pressure upon the operatingspringhas been released.

2. A spring-operatedclosingdevice for adredg -v ing can, mounted upon acontainer body, com-3 prising a hollow cylindrical outer member. and aninner slidable sleeve member, the saidinnersleeve being wholly open atone end and .closed by a top wall at the other end and provided withlater.-

so disposed and adapted to registerwith. the aperturesof the innerslidable sleeve when the latter' isfully depressed intooperativeposition, but to be fully closed by the unperforatedportions.of r the side wall of the inner slidable sleeve when the same is allowedto returnto its 'normal' position by. release of pressure exerteduponits closed top. wall through the opening in the top wall of the:

outer member, through the'action of a helical spring longitudinallyplaced within the hollow of the inner slidable member, the lower. end ofsaid' 1 spring resting upon the inwardly turned lugs of the said outermember and at its upper end against the closed topw'all of'the.lnnerslidable than the outer member, the outer member being provided atits upper and lower ends with means:
